N-Heterocyclic Carbene Catalyzed Nucleophilic Substitution Reaction for Construction of Benzopyrones and Benzofuranones
摘要:
N-Heterocyclic carbene as an efficient organic catalyst was employed to catalyze an intramolecular nucleophilic substitution reaction. When R-2 was a phenyl group, the cyclization process underwent isomerization, leading to generation of benzofuranone.
